IMPROVEMENT IN GAGES.

Specification forming part of Letters Patent N0. 19] .053, dated May 22, 1877 application filed January 30, 1877.

To all whom it may concern:

Be it known that I, FRANK K. HESSE, of

- Boston, in the county of Suffolk and State of Massachusetts, have invented a new and useful Improvement in Ualipers, which improvement is fully set forth in the following specification and accompanying drawing, in which- Figure 1 is a plan View of calipers embodying my invention. Fig 2is a side view of the same.

Similar letters of reference indicate corresponding parts.

The object of this invention is to combine, with inside and outside calipers, a wire-gage, each having its index-finger and graduated scale;

a represents the calipers, a, a being the outside, and a a the inside, calipers. b is a screw, running in the slot 0, for securing the calipers at any point. d is the caliper indexfinger, and k the scale, by inches and fractions thereof, indicating the measurement.

6 is a post or projection attached to the leg a, and projecting through the slot 1. e is a similar post, projecting from the leg a. These posts constitute a wire-gage. The wire or metal is placed snugly between them, and the index-finger 9 indicates upon the graduated scale h the number of gage. Both the indexfingers h and k project from the armo Thus, it will be seen that in a single instrument both the calipers and wire-gage are provided.

Of course, I do not claim as my invention the calipers a a a a on the index-finger d; but What I claim, and desire to secure by Letters Patent, is- V In combination with the calipers a a, a 11, provided with the index-finger d and graduated scale k, the wire-gage e 6, attached to the legs a a, the former projecting through the slot 1, the index-finger g, and graduated scale it, all combined and arranged substantially as and for the purpose herein described.

FRANK K. HESSE.
